How to Set Time Delay in JavaScript
Topic: JavaScript / jQueryPrev|Next
Answer: Use the setTimeout() Function
You can use the setTimeout() function to set time delay before executing a script in JavaScript. This is a reliable way to put time delay without blocking the UI since it is an asynchronous function.
Let's try out the following example to understand how it basically works:
Example
Try this code »<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Execute Script after a Delay in Javascript</title>
</head>
<body>
<p>If you click the button alert will show after 2 seconds</p>
<button type="button" onclick="showAlert();">Show Alert</button>
<script>
function showAlert(){
var delayInMilliseconds = 2000; // 2 seconds
setTimeout(function() {
alert("Hi there!");
}, delayInMilliseconds);
}
</script>
</body>
